Improvement in cake-pans



UNITED STATES ATENT OFFICE.

l JOHN HARRY SMITH, OF BROOKLYN, NEW YORK.

IN CAKE-FANS.

Specification forming part of Letters Patent No. l05.992, dated August 2, 1570.

To all whom it may concern:

Be itknown that I, J. H. SMITH, of Brooklyn, `in the county of Kings and State of New York, have invented a new and Improved Cake-Pan; and I do hereby declare that the following is a full,l clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of l this specification.

lIhis invention relates to s'pirally-corrugated cake-pans; and it consists in an improved article formed of tin struck up into the shape desired.

Heretofore these articles have been manufactured of copper or sheet-iron, and were forged or hammered into shape. The material employed and the expense of forging it into shape have rendered them very expensive to those who use them, and I therefore propose to introduce to the public an article whose rst cost will be greatly lessened, while its durability will, it is believed, be lessened but little, if at all.

The drawing represents a cake-pan having a shell spirally corrugated and a Ventilatingtube. These deep spiral corrugations obstruct the action of the dies on the metal, and have heretofore deterred any attempt to form them with spiral corrugations up to the tube, and of tinware.

Having thus described all that'is necessary' to a clear understanding of my invention, what I esteem as new, and desire to protect by Letters Patent, is-

As a new article of manufacture, a spirallygrooved cake-pan formed of tinware struck up in the manner described.

The above specification of my invention` signed by me.

J. HARRY SMITH. Witnesses:
